AGENIUM — Agent-to-Agent Communication SDK (Python)

Local, stateful agent-to-agent communication using the agent:// protocol.

Quick Start

pip install agenium

Create an Agent

import asyncio
from agenium import Agent

async def main():
    # Create and start an agent
    agent = Agent("my-agent")
    
    # Register a tool
    @agent.tool("greet", description="Greet someone")
    async def greet(name: str) -> str:
        return f"Hello, {name}! I'm {agent.name}."
    
    # Start listening
    await agent.start(port=8443)
    
    # Register on the AGENIUM DNS
    await agent.register(api_key="dom_your_key_here")
    
    print(f"Agent running at agent://{agent.name}")

asyncio.run(main())

Connect to an Agent

import asyncio
from agenium import Agent

async def main():
    agent = Agent("client-agent")
    await agent.start()
    
    # Resolve and connect
    session = await agent.connect("agent://my-agent")
    
    # Call a remote tool
    result = await agent.call_tool(session.id, "greet", {"name": "World"})
    print(result)  # "Hello, World! I'm my-agent."
    
    # Send a message
    await agent.send(session.id, "ping", {"data": "hello"})
    
    await agent.stop()

asyncio.run(main())

DNS Resolution

from agenium.dns import DNSResolver

resolver = DNSResolver()
agent = await resolver.resolve("my-agent")
print(agent.endpoint)  # https://1.2.3.4:8443
print(agent.tools)     # [Tool(name='greet', ...)]

Features

• agent:// Protocol — URI-based agent addressing (agent://name)
• DNS Resolution — Automatic agent discovery via AGENIUM DNS (185.204.169.26)
• Stateful Sessions — Persistent sessions with SQLite storage
• Tool System — Register/invoke tools across agents
• mTLS Security — Mutual TLS with auto-generated certificates
• Capability Manifest — Agents advertise their tools in DNS
• Async-First — Built on asyncio and httpx

Architecture
